| The Superconducting Linear Accelerator as a booster of existing 15 UD Pelletron accelerator is under construction at IUAC. The heart of superconducting linac is three cryomodules, each one housing eight quarter wave niobium cavities. At present the first linac module along with superbuncher and rebuncher cryostat are integrated with zero degree beam line. Design and fabrication of two more linac modules under progress. A VME based CRYO-DACS has been developed to monitor and control parameters of cryostat. The total load at 4.2 K for complete system including locally developed liquid helium distribution line as well as break up load for each cryomodules has been measured. The measured load in linac module is higher than the design value. A detailed thermal analysis has been carried out using temperature profile for each component of cryomodules. Extra load is mainly contributed by aluminum structure,drive coupler and additional radiation load. The present paper will be highlighting the operating experience on cool down of linac as well as thermal performance of each cryo module. Scope of improvement on future linac cryo module to reduce the static load will also be covered. |
